Windows 7: Essentials update

Last night I had an update for Windows Essentials or maybe Microsoft essentials. I checked in windows updates but it wasn't listed there so I clicked the update icon and as it was doing it's thing, I cancelled it because I realized I don't have MS essentials. I only have Windows Defender and Windows Live Mail 2011 on the computer. But now, am wondering if I did the wrong thing.
If I do need it because of defender and wlm...could you please tell me how and where I can find this update now?

I was going to run a scan with PSI from Secunia to see if maybe they would find something that was not updated, but I couldn't find the one that you just scan but don't have to download and install it. Could you please direct me to the scanner?

Answers to these two questions would be most appreciated. Thanks.

Secunia online Scanner.

Go to 'Programs and features' click Windows Live Essentials and do a repair.

MSSE is a free AV from microsoft for win 7 and that one replaces Windows defender in this win 7 release if installed and WD will be back with the release of windows 8.
So it's better to let WU to handle needed updates.

Secunia is not an ant-virus in the conventional sense - and Defender in Windows 7 is not an Anti-Virus in any sense of the term.

What actual Anti-Virus do you have installed?

if the answer is 'None' then you should back up your data to external storage, and then reformat and reinstall your OS.

You received that MS Live Esentials update because you have Windows Live Mail which is one of the prorams offered in Windows Live Essentials.
There is a new WLM version.... build 15.4.3555.0308
Have a look at your WLM version....
Open WLM > click the blue button at top left > About > what version does it say ?
I bet yours is not the same.

You should have accepted the updates. It would have updated your WLM, and it wouldn't and couldn't update any Windows Live Essentials programs that you don't have. You have nothing to worry about accepting the update.

veegee,
You could wait for next time it prompts you for an WLEssentials update. It will. I had this happened to me. I know.

Or,

You can go online and download it...

Thanks for everyone's help.
I ran the Secunia OSI scan, result was 'no errors'. Ran repair on windows essentials in ctrl panel and some time later the update reappeared, so clicked on it and it disappeared. Did another repair but it never returned.

I am aware that OSI is not an AV. What I meant was the only MS programs I use are windows defender and WLM (& unfortunately MS firewall also).
I think what concerned me the most was how I got stuck with WLM 2011 in the first place; because MS said it was a "very important" update and I stupidly didn't research it before accepting it (an update with a jillion other junk that I would never use), and I thought what more goodies might be in store with this update. Just give me the old windows mail and I would be happy.

t-4-2 Thanks for explaining this - has sure set my mind at ease. My WLM version is 15.4.3538.0513.

So, your WLM is out-dated.

You want to wait for next update or you want to download the current version now...... It's your call.

If you are only running with Windows Defender, then you have no antivirus - and that is almost criminal in this day and age, unless you are an expert.
I will refrain from adivsing a reformat/reinstall - gut it is something you should consider.

Whatever you do, you MUST install a proper Anti-Virus program, or you risk not only your own machine and data, but any machine yours comes into contact with in any way, and anyone whose email address or other data you have on file

There are many Free AV's out there - some good, some not so good. The ones I have experience of that are good, are MSE and Avast. I have started to actively dislike AVG, because of bloat.
